How to Re-Stock a Ship in Half an Hour

Have you ever seen a documentary about those mammoth cruise ships that come into port and only have five hours to unload, clean, re-stock and re-load before they head out again on their next voyage? When they show the re-stocking activities they have to speed up the cameras to catch all the action as staff scramble in and out with forklifts and the re-stocking is done continuously during those five hours!

If they pre-stocked the Cargo Carousel System with supplies and then swapped them out with the empty Carousels (or full of recyclables) they could completely replenish the ship in half an hour! This would work well for the Navy too.
